Key fobs are a popular way to restrict access to buildings, and areas within them, as well as store information that makes them very popular for businesses. Whether it’s in an office or hotel security system to limit access to the designated areas or a business looking for a more convenient membership or rewards scheme, key fob cards are a great choice.

At Precision Card Services, we specialise in a range of plastic cards for a number of different situations and uses and our key fob cards are just as inclusive in the number of options available. With different packages and card/fob functionality available, we can cater to your needs.

Typically, key fobs and their cards work by making use of a bar code and a scanner to access what’s on the card or, as in the case with the fob, a sensor to read when it is in close proximity and to open the assigned doors or areas to the holder.

These cards and fobs can be programmed with ease so once they have been installed then you can alter them as needed and new ones are only needed when you run out, not every time a change is made, which can make them very valuable in the long-term.
